Application led April 25, 1925. Serial No. 25,820.

This invention relates to certain improvements in knives and it is an object of the invention to provide a device of this general character constructed in a manner whereby undue stress on the wrist is avoided when the knife is being employed.

Another object of the invention is to provide a knife of this kind comprising an elongated arm having a cutting blade at one end portion and a handle at the opposite end portion, said handle being so positioned with respect to the longitudinal axis of the arm to permit the requisite use of the knife without unduly tiring the user.

The invention consists in the details of construction and in the combination and arrangement of the severalparts of my improved knife whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accomaanying drawings, wherein Figure l is a view in side elevation illustrating a knife constructed in accordance with an embodiment of my invention;

Figure 2 is a view in plan of the blank from which the handle as herein disclosed is formed;

Figure 3 is a View in elevation of the knife blade as herein disclosed;

Figure -1- is a fragmentary sectional view taken through the handle. p

is disclosed in the accompanying drawings, l denotes an elongated arm of requisite dimensions and which has securedat one end portion a cutting` blade 2. A side marginal port-ion a of the blade overlies a side face of the arm l and has directly engaged therewith the members 8 for attaching the blade 2 to the arm l, said members 3 being of any desired character and removable if preferred.

The opposite side marginal portion of the blade 2 is provided with a cutting edge Z) which is disposed on an angle with respect to the longitudinal axis of the blade 2 and which, when the blade 2 is in applied position, extends to the adjacent side face of the arm 1. The blade 2 is preferably applied to the arm l with the cutting edge thereof disposed on an inward incline with to said arm l.

Secured to the opposite end portion of the arm l. or that portion remote from the applied blade 2 is a handle H including a hand hold l, herein disclosed as angularly disposed with respect to the arm l and at an angle of approximately, sixty degrees although I do not wish to be understood as limiting myself in this particular as the position or angle of the hand hold t will be dependent upon the character of work for which my knife is to be used.

it is to be noted'that Jthe major portion of the hand hold l is disposed to the side of the longitudinal center of the arm l in which the applied blade 2 is directed so as to bring the center of said hand hold in substantial alignment with the center of the cutting edge 7) of the blade 2 to avoid stress'on the wrist of the user during a working 0peration and therefore prevent undue tiring of the operator.

As is particularly illustrated in Figure 4, the handle H is formed from a single blank of material comprising a central plate 5 of requisite dimensions and which has extending from each side thereof an arcuate meinber 6, said member extending from end to end of the plate 5 and integrally formed therewith. Each of the members 6 at a desired point thereon is provided with an outstanding web 7, said webs being adapted, when the blank is properly folded or formed, to overlie the opposite side faces of an end portion of the arm l and be secured thereto by the suitable members 8. y

rEhe blank in forming the handle H is folded along the longitudinal center of the plate 5 and the marginal portions of said plate are then turned inwardly intooverlapping relation, as indicated at 9 in Figure 4, whereby the hand hold 4 is of substantially a cylindrical formation. This bending or forming of the hand hold e is facilitated b v aroviding the side marginal portions of the plate 5 immediately adjacent the extremities of the arcuate members 6 with the open slits l0.

A knife constructed in accordance with my invention is particularly adapted for snapping corn, topping kalir corn as well as for other purposes. As disclosed in the accompanying drawings, the blade 2 is applied for use in particularly snapping corn. In topping kafir corn this blade 2 is preferably disrespect posed beyond the opposite longitudinal margin of the arm l.

Each of the Webs 7 is arranged to one side of the center of the associated arcuate member and has its longitudinal axis inclined toward the end of said arcuate member remote from the Web so that when the Webs 7 are engaged with the arm l the folded portion or hand hold Will be inclined With respect to the longitudinal axis of the arm l.

l find it of particular advantage to have the cutting edge Z) of the well known sickle edge type and by such use the etiiciency of the knife is materially increased.

Frein the foregoing description it is thought to be obvious that a knife constructed in accordance with my invention is particularly Well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification Without departing from the principles and spirit thereof and for this reason l do not wish to be understood as limiting myself yto the precise arrangement andformation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.'

I claim n combination with an arm, a handle attached to an end portion thereof, said handle being formed from a single blank of material comprising a central plate having extending from each side thereof an arcuate member, said arcuate member extending from end to end of the plate, each of said arcuate members being provided With an outstanding web, said web being arranged to one side of the center of the arcuate member with its longitudinal axis disposed on an incline in a general direction toward the opposite side of. the arcuate member, said blank being folded along` the longitudinal center of vthe plate, the Webs overlying the opposite faces of the arm, and means for securing said Webs to the arm, the side longi tudinal margins of the plates immediately adjacent the extremities of the arcuate members being provided with slits permitting the longitudinal marginal portions of the plates to overlap, the relation of each of the Webs with respect to its associate arcuate member inclining the longitudinal axis of the folded port-ion of the plate with respect to the arm.

In testimony whereof I hereunto aiiix my signature.

CHARLES H. SCHETZER.
